--- Comment #3 from Zhang Rui (rui.zh...@intel.com) ---
Method (VBDL, 0, Serialized)
{
ADBG ("VBDL")
PB1E |= 0x20
ADBG ("VBDL EN")
If (CondRefOf (\_SB.PWRB.PBST))
{
\_SB.PWRB.PBST = 0x00
Notify (\_SB.PWRB, 0x01) // Device Check
}
VBTN = 0x01
\_SB.PCI0.LPCB.EC.B10E = 0x01
RSDE = 0x01
}
when PBST is set, we're using ACPI Power Button, PWRB._STA returns present, and
notifications are sent to PWRB device.
when PBST is cleared, PWRB is gone and the power button events are sent to
another device,
Method (_Q75, 0, NotSerialized) // _Qxx: EC Query, xx=0x00-0xFF
{
If (((OSYS >= 0x07DF) && \_SB.HIDD.BTLD))
{
ADBG ("Notify _HID 0xCE")
Notify (\_SB.HIDD, 0xCE) // Hardware-Specific
}
ElseIf ((\_SB.PWRB.PBST == 0x01))
{
Notify (\_SB.PWRB, 0x80) // Status Change
\_SB.PWRB.PBLV = 0x01
}
}
Device (HIDD)
{
Name (_HID, "INT33D5") // _HID: Hardware ID
...
}
HIDD is the intel-hid device, so please make sure if you have intel-hid driver
is built or not (CONFIG_INTEL_HID_EVENT).
